| The main objective of this study was to determine the impact of three organic strategies (organic compost, green manure and dry mulching) on soil’s physical behaviour, vine physiology and grapevine quality, from 2015 to 2017, within two vineyards: FF and SD. The degraded areas chosen had significant higher disruption of the soil, lower yield, but also lower quality of the grape. The two-years application of compost improved significantly the soil structure, the nitrogen and hydric status of the vine. The dry mulching and the green manure didn’t have significant impact. The vintage effect must be taken in account as the climatic conditions from 2015 to 2017 were heterogeneous and the vintage 2017 particularly dry. However, the treatment impact is proved by... |
